Percent = share of the energy proxy a permanent hot spot would absorb in the same time. Spacing is computed from c/2f. No measured oven data is shown.
Model notes & sources
Field. A 1D standing-wave slice across the oven: time-averaged intensity I(x) = cos²(2πx/λ), λ = c/f. Bright planes sit every λ/2 (6.12 cm at 2.45 GHz) and stay fixed in the oven. Frequency is a model-only control; household ovens commonly use about 2.45 GHz.
Dose. Each 0.8 cm food tile adds up I over time (seconds at peak intensity). That is a relative absorbed-energy proxy, not a temperature: no absorption depth, water content, conduction, steam or edge heating are modelled.
Turntable. One turn per 12 s; a tile at (x, y) sits at x(t) = x cos θ − y sin θ. Dose is integrated on a fixed 1/60 s Simpson timeline, so any time renders the same way. Over a full turn a tile at radius r averages (1 + J₀(4πr/λ))/2: stripes become rings, and the axis never moves.
Limits. Real cavities are 3D and multimode, often with mode stirrers, and the pattern depends on the oven, the load and its position. Not every oven has this field, and a turntable does not guarantee even heating. This is not food-safety guidance.
